SUTTONS BAY, Mich. Dozens of federal agents with help from Michigan authorities have raided two sites in the northern Lower Peninsula, taking precautions for possible exposure to hazardous chemicals.
The Leelanau County Sheriff's Department says about 60 federal agents are participating in the investigation, which led to raids Friday in Suttons Bay and Leelanau Township.
Sheriff Mike Borkovich says in a Web posting that "other searches are being conducted related to the case in other states."
He didn't identify those states.
FBI spokesman Robert Beekman in Detroit confirms the Michigan raids but says the affidavits that let to them are sealed and so he can't disclose any information about links to raids elsewhere.
